Grape Varieties: Hondarribi Zuri
Surprisingly, due to the everyday style of Txakoli being 'spritzy', there isn't a lot of sparkling wine made in the region. However, K5 realised the potenital of their indigenous grape and decided to give it a try.
They have used only grapes from one of their older vineyards, Soroberri, as it is more Westerly than others (most being North-facing), and with poorer organic material in the soils, and so ripens a little earlier. This actually mean they can ahrvest a little earlier and still get great fruit ripoeness but also the acidity needed for a sparkling wine - Not that difficult with Hondarrabi Zuri!
Their winery method is almost as for a Pet-Nat, but although the primary fermentation finishes in bottle, they do a disgorgment, meaning the wine is clear and crisp. All processes are done by hand, and they had to do the transer to bottle at 2 a.m. to get the right amount of fizz in the final wine!
